B. `Rnf^(13)6d^(1)7s^(1)7p^(2)`
C. `Rn5f^(14)7s^(1)7p^(1)`
D. `Rn5f^(14)6d^(1)7s^(2)`

Answer

To determine the outer electronic configuration of Lawrencium (Lr), we need to follow these steps:

### Step 1: Identify the Element
Lawrencium is the element with the atomic number 103 and is part of the actinide series.

### Step 2: Understand the General Electronic Configuration for Actinides
The general electronic configuration for the actinide series is:
- 5f¹⁴
- 6d⁰ or 6d¹
- 7s²

### Step 3: Determine the Specific Configuration for Lawrencium
For Lawrencium (Lr):
- It has 14 electrons in the 5f subshell (5f¹⁴).
- It has 1 electron in the 6d subshell (6d¹).
- It has 2 electrons in the 7s subshell (7s²).

### Step 4: Write the Complete Outer Electronic Configuration
Thus, the complete outer electronic configuration of Lawrencium is:
- 5f¹⁴ 6d¹ 7s²

### Conclusion
The outer electronic configuration of Lawrencium is **5f¹⁴ 6d¹ 7s²**.
